It's all opinion and in my opinion there is a market for more compact kit and no, the f1.8 is not a replacement for the same reason. The mini G's are. On the zoom side there is the collapsible kit lens and it is lovely and compact but it's more limited aperture wise.
Your other comments. You should keep your mild personal slights to yourself or aim them at someone who gives a flying what you think but then you do tent to run off at the mouth a bit and come out with OTT drivel too often. IMO of course. I don't want to have to waste my time replying to garbage like this from you. Here's a bit of advice... Try and be funny instead of just
funny.
A7 with 35mm f2.8 v 24-50mm f2.8 which I thought might be one of the smaller f2.8 zooms.

That could make a difference on a day out or holiday and I think Sony see a market for smaller kit as they have some small primes and the A7c range which I think is selling well for them.
I can see how some wont mind about extra bulk and weight and I can see how some might not want to be limited to a f2.5/f2.8 prime but I also have small f2 and even a f1.4 prime. I am happiest with primes. On the general point of bulk and weight even someone who tends to suffer from verbal incontinence might be able to at least perceive that some people might light compact and light kit. I hope so.
